First, for a given amount of cement in the mix, crushed limestone concrete will have an approximately 10 strength advantage. This strength advantage comes from the fact that cement bonds tighter to limestone than to a slick smooth gravel and the strength that is derived from the sharp angular faces of the crushed aggregate. Second, because crushed limestone has a lighter unit weight than gravel, it.
